Abstract
The invention provides a novel process for preparing vegetable oil from oil crops with a steam explosion-aqueous solvent method. The novel process comprises the steps of: firstly, feeding preimpregnated raw materials into a steam explosion tank, introducing saturated steam (with the pressure reaching 5-15Kg/cm<2>), preserving the pressure for a period of time (1-10min), and then quickly exploding to obtain steam explosion slurry; and then, freezing the steam explosion slurry, standing overnight, defreezing, and adding a certain amount of hot water or/and composite cellulose for oil extraction with an aqueous solvent method, wherein the oil extraction rate reaches 62.26-81.18%. The vegetable oil extracted with the steam explosion-aqueous solvent method has the characteristics of pure color, limpidity, transparency, natural and pleasing flavor and good quality. The novel process provided by the invention for preparing the vegetable oil is suitable to various plant oil raw materials, is beneficial to simplification of an oil seed treating process and solution to the problems of high energy consumption for mechanical pulverization, high treating cost and difficulty in propagation in the traditional process for preparing the vegetable oil with the aqueous solvent method, and has great importance for industrial production of preparing the vegetable oil with the aqueous solvent method.
Description
Technical field
The invention belongs to the extractive technique field of edible vegetable oil, particularly raw material is carried the preceding quick-fried treatment technology of vapour of oil.
Background technology
Vegetables oil derives from the seed of plant mostly, contains necessary unsaturated fatty acids of human body such as linolic acid, linolenic acid, oleic acid etc., and being that human body institute is essential takes in and indispensable food.The main source of vegetables oil is a yearly plant, as soybean, peanut, rape and corn; Perennial oil plant seeds are also arranged, as walnut, oil tea, palm and olive.
Vegetable oil extraction technology mainly contains milling process, lixiviation process and aqua method at present.Need before squeezing or the leaching oil plant is carried out processing such as fragmentation, pulverizing, press for extracting juice embryo or baking, destroy the oil plant cellularstructure, reach favourable fuel-displaced condition with methods such as machinery and heating power.And the external power effect of vegetable cell has very strong resistibility, and is therefore limited to the destructiveness of vegetable cell, and simultaneously, adhesion is agglomerating easily in crushing process for the high plant of oil length, brings difficulty to operation.In addition, it is big that the solvent extraction method is put forward oily potential safety hazard, and cause the acid value height easily and dissolvent residual is arranged, and the processed oil quality is lower, and edibleness is affected, so price is usually not as good as pressed oil.Aqua method comprises that water reaches the aqueous enzymatic method that grows up on its basis for method, and water is for method less investment, simple to operate; Aqueous enzymatic method mild condition, extraction time are short, but the two is not used widely, and still are in the laboratory study stage so far.Reason also is not only extracting method itself, but lack preferably, supporting raw material pretreatment process with it.
At above problem, this patent is introduced the steam explosion preconditioning technique, carries out producing of vegetables oil in conjunction with aqua method, set up vapour quick-fried-aqua method produces the novel process process of vegetables oil.Vapour is quick-fried can be realized at short notice to the boiling of raw material and quick-fried broken, sample preparation homogeneity height, and crushing effect is good, and has shortened pretreatment time greatly, the high energy consumption of having avoided mechanical disintegration to bring; Aqua method is carried oil tech and is had simple, the safe and reliable and economic characteristics of technology, and the vegetables oil quality better that makes can reduce refinement step to a great extent, reduces the refining cost, meets everybody simultaneously for healthy and safe requirement.
Summary of the invention
The objective of the invention is for solving the problem that the mechanical disintegration energy consumption is big in the traditional aqua legal system oil process, tooling cost is high, be difficult to amplify, the integrated and innovation by technology, made up vapour quick-fried-aqua method produces the technical matters of vegetables oil.
The technical scheme of this patent is as follows:
The vapour that this patent relates to is quick-fried-and aqua method produces the novel process of vegetables oil, key step comprises: 1) steam explosion: the preimpregnation of raw material water, the preimpregnation condition is: soak 6～12h under the room temperature, make its water content reach 30～50%, drop in the steam-explosion jar then, feed saturation steam and keep different pressures, pressure release discharges behind the certain hour, collects the quick-fried back of vapour material; The quick-fried condition of vapour is 5～15Kg/cm
2Keep 1～10min; 2) the quick-fried slurry freeze overnight of the vapour of Shou Jiing, the back that thaws adds 40～60 ℃ of hot water or/and complex cellulase, and the magnetic agitation vibration is extracted, and rotating speed is 100rpm, forms tangible layering until water oil; 3) collect oil reservoir.
This patent vapour is quick-fried-and aqua method produces the novel process of vegetables oil, has the following advantages:
(1) introduces the quick-fried technology of vapour raw material is carried out pre-treatment, integrate grease and produced oilseeds pulverizing and two processes of wet heat treatment in the industry, overcome the drawback when pulverizing complicated loaded down with trivial details, consumption energy consumption such as strip plate, damp and hot steaming stir-fry in traditional oil plant pre-treatment, set up new and effective oil plant treatment technology technology;
(2) adopt aqua method to extract vegetables oil, formed the vegetables oil reparation technology of cleanliness without any pollution;
(3) the integrated and innovation by technology, made up vapour quick-fried-aqua method produces the technical matters of vegetables oil, solved the problem that the mechanical disintegration energy consumption is big in the aqua legal system oil process, tooling cost is high, be difficult to amplify, significant to the suitability for industrialized production of aqua legal system oil.
